Dandre read 5 books deacon read 6 books and breanna read 7 books. one book was read by all three children but every other book was different. how many different books did the children read?

4+5+6+1 = 16 books

crab crab crab it makes me write 20 characters crab crab crab

16 books

Step-by-step explanation:

Books Dandre read: 5 -1

           Deacon read: 6 -1

            Breanna read: 7 -1

There is one book every one read.

But when you subtacrt one from each, you also need to add 1 to count that book that everyone read.

4+5+6+1

=9+6+1

=16 books

Hope this helps.

Please consider brainliest, thanks!!!

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week
